The G-series is a pretty basic camera with conventional controls.Put the camera through it's paces at home with the manual handy for reference and it's unlikely that you'll need to reference it that often in the future.

I printed the manual (all 214 pages!) with 2 pages per page and double-side printing, but ultimately found it easier to read the pdf on-screen. I agree with the previous comment, that the G series is fairly intuitive to operate (as are most Canons). But it is helpful to have the manual for the few new gems you might find. I do miss the tidy little booklet!
